What Causes the Steering Wheel Not to Return to Center After Turning?
1 Answers
Steering wheel not returning to center after turning may be caused by damage to the external steering gear. Below is relevant information about the external steering gear: Introduction: In vehicles equipped with power steering systems, the energy required for steering is primarily provided by the hydraulic (or pneumatic) energy from an engine (or motor)-driven oil pump (or air compressor), with only a small portion coming from the driver's physical effort under normal conditions. Types: Based on the transmission medium, power steering gears can be categorized into pneumatic and hydraulic types. Pneumatic power steering gears are not suitable for extra-heavy-duty trucks because the working pressure of pneumatic systems is relatively low (generally not exceeding 0.7MPa), making the components excessively large when used in heavy vehicles. In contrast, hydraulic power steering gears can operate at pressures exceeding 10MPa, resulting in much smaller component sizes. Hydraulic systems operate quietly, with minimal response lag, and can absorb shocks from uneven road surfaces. As a result, hydraulic power steering gears have been widely adopted in various types of vehicles.
